I got to level 29 and am stuck, I know what I need to do to win this level but it requires a re-spec of my skill points. I have an effective setup, my skill configuration has been great through level 29, but I can't beat it because I don't have a required skill which would make this level very easy to beat. I love this game, but I'm not about to start all over from level 1.
Bottom line, this game needs a respec feature, it would be awesome to be able to reconfigure skill points (like you can in Protector. Look, Protector is the #3 currently top most popular game on here, and the ability to reconfigure skill points at will is a very key and important feature which is what makes the game so fun and successfully popular. This is the one thing missing in this game. So in my case, rather than getting stuck on a level and having to attempt dozens of times in vain to beat level 29, and then finally realizing that I failed to acquire a key skill necessary for beating this level.
